PRODUCTION DATA
This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and measured using a two-step method. First, the gain is determined by (Equation 2).
where
The offset voltage is then measured at VSENSE = 100 mV and referred to the input (RTI) of the current shunt monitor, as shown in (Equation 3).
In GUID-DB3CDEB3-CF31-4CD4-A2A4-13992281C45A.html#GUID-DB3CDEB3-CF31-4CD4-A2A4-13992281C45A, the Output Error vs Common Mode Voltage curve shows the highest accuracy for the this region of operation. In this plot, VS = 12 V; for VCM ≥ 12 V, the output error is at its minimum. This case is also used to create the VSENSE ≥ 20 mV output specifications in the Electrical Characteristics table.
